Cutaneous mucormycosis in a heart transplant patient associated with a peripheral catheter.

The first known case of an intravascular catheter-related primary cutaneous mucormycosis in a heart transplant patient is reported. The patient had corticosteroid-induced hyperglycemia and experienced an acute tissue rejection episode. A necrotic lesion appeared around the insertion site of a peripheral venous catheter. A biopsy revealed typical mucorales hyphae. The lesion continued to spread during the following 24 hours and necessitated amputation of the forearm. The organism was identified as a Mucor species.

Gastrointestinal mucormycosis.

Mucormycosis is an acutely malignant fungal disease causing local thrombosis and infarction. Gastrointestinal infection most commonly occurs in diabetics or in the immunologically compromised. This case demonstrates the radiological appearances of the gastrointestinal lesion and prolonged survival with amphotericin-B therapy.

Aeromonas hydrophila myonecrosis accompanying mucormycosis five years after bone marrow transplantation.

A 36-year-old man, five years after bone marrow transplantation for aplastic anemia, was admitted with myonecrosis of the forearm after he had immersed his hand in sewage water several days prior to his admission. Blood cultures and specimens taken from the necrotic tissue of the arm all grew Aeromonas hydrophila. Following extension of the infection, the patient underwent amputation of the arm but ultimately died of cerebral mucormycosis. The epidemiology of Aeromonas infections is discussed and the literature of Aeromonas myonecrosis is reviewed.

Rhino-orbital-cerebral mucormycosis in type 1 diabetes mellitus.

AIM: To describe the presentation and outcome of rhino-orbital-cerebral mucormycosis (ROCM) in adolescents with type 1 diabetes mellitus (T1DM). METHODS: The medical records of six patients of T1DM with ROCM admitted between October 2001 to January 2004 were analysed. RESULTS: The mean (+/- SD) age and duration of DM of these patients were 16.1+/-3.0 years and 26.3 +/- 24.9 months respectively. Four patients had ROCM at presentation, while two developed it during their hospital stay when recovering from diabetic ketoacidosis. Proptosis (100%) and ptosis (100%) were the most common symptoms, and ophthalmoplegia (85%) and vision loss (85%) were the most common signs. Maxillary sinus (85%) was the commonest paranasal sinus to be involved. All patients received amphotericin B and had appropriate surgery except one. Four patients survived. Patients who had altered sensorium, facial necrosis, palatal perforation and cerebral involvement at presentation had poor outcome. CONCLUSION: High index of suspicion of ROCM in T1DM and combined approach with amphotericin B and appropriate surgery is rewarding.

Invasive colonic mucormycosis in early induction therapy of childhood acute lymphoblastic leukemia.

Fungal infections occur in patients who are severely immunocompromised with profound and prolonged neutropenia. We report a patient of acute lymphoblastic leukemia who developed nonspecific abdominal symptoms within two days after the onset of neutropenia in the early induction phase of chemotherapy, which was later found to be due to intestinal mucormycosis and resulted in a fatal outcome.

Lessons to be learned from a complicated case of rhino-cerebral mucormycosis in a renal allograft recipient.

Fungal infections still represent a serious complication after organ transplantation. Early diagnosis and aggressive treatment are crucial. Because of the many diagnostic problems involved, we present a case of mucormycosis--primarily affecting the paranasal sinuses with later intracranial extension--in a highly immunized recipient of a third renal transplant. Although fungal infection was suspected from various imaging techniques, only the detection of typical fungal hyphae in the infected tissue was diagnostic. Neither the blood tests and cerebrospinal fluid examinations performed nor cultures from maxillary sinus fluid were of any diagnostic help. Surgical debridement from a transnasal as well as an intracranial approach and systemic amphotericin B together with the discontinuation of immunosuppression after removal of the rejected graft were able to save the patient. This case stresses the importance of early diagnosis that can only be made from tissue biopsies and allows appropriate timely treatment.

Mucormycosis of the renal allograft: case report and review of the literature.

Fungal infection is an uncommon complication after renal transplantation. We describe a rare form of mucormycosis in the renal graft. Our method was to review chart data and to perform medline searches. The patient was a 42-year-old man who underwent living-unrelated kidney transplantation in Egypt and returned to Israel on POD 8. Within the ensuing 4 weeks he experienced acute rejection which responded to treatment with steroids. Few days after discharge he was readmitted because of fever and graft dysfunction. An infected large perigraft collection was drained, but the patient became anuric and septic. Kidney biopsy showed infarcted necrotic tissue infiltrated by fungi which grew Mucor species. Despite initial improvement following graft nephrectomy and antifungal treatment the patient died of sepsis. Literature review revealed only three additional cases of graft infection due to Mucorales. We conclude that Renal graft infection due to Mucorales is an extremely rare and potentially lethal complication. Living unrelated donation in third world countries might be a possible risk factor. Fungal colonization may occur during transplantation. A high index of suspicion, leading to early diagnosis and initiation of antifungal treatment, in addition to graft nephrectomy, are keys to a more favorable outcome.

Isolated pontine infarction due to rhinocerebral mucormycosis.

We report a patient with rhinocerebral mucormycosis whose initial central nervous system involvement was isolated pontine infarction due to basilar arteritis caused by the fungus. The patient was diagnosed and followed by MRI and CT and basilar arteritis was demonstrated well on MRI studies. Involvement of the skull base was shown on CT in the later stage of the disease. The unusual initial presentation of the infection is discussed.

External Iliac artery stent mucormycosis in a renal transplant patient.

A Mucorales infection of an external iliac artery stent in a renal transplant patient is described. Following a kidney transplantation operation and an acute rejection of the transplant, an aneurysm developed at the site of the arterial ligation and three stents were inserted. Two months following insertion of the stents, recurrent episodes of peripheral thromboembolism occurred. Histological examination of the thrombus revealed hyphae characteristic of mucormycosis. A combination of surgical and medical treatment with intravenous liposomal amphotericin B was applied, which led to complete cure of the disease without infection recurrence after 1 year of follow-up.

Mucormycosis: ten-year experience at a tertiary-care center in Greece.

Presented here are the results of a retrospective analysis of all mucormycoses infections recorded at a tertiary hospital in Greece during the last 10 years. A total of 24 patients were identified, 15 male and 9 female, with ages ranging from 37 to 80 years. Twelve of the patients had soft tissue infections (2 with concomitant pulmonary infections), and 12 had rhinocerebral infections. Transmission could be traced in two cases; to nitroglycerin patches in one patient and to a lemon-tree-thorn scratch in the other. Among the 17 patients who underwent surgery, 11 survived. All seven patients on whom surgery was not performed died. Rapid diagnosis and treatment of mucormycosis are essential for patient survival. The severity of the patient's underlying condition, the degree of immunosuppression, and prompt surgical treatment are the most important factors contributing to the outcome.

Disseminated mucormycosis caused by Absidia corymbifera leading to cerebral vasculitis.

An 18-year-old woman was admitted to hospital because of subcutaneous hematoma and fever of unknown origin. Acute myeloid leukemia was diagnosed and empirical antimicrobial treatment and induction chemotherapy were started. After initial defervescence, fever relapsed 2 days after the onset of neutropenia. The CT scan of the lung was consistent with an invasive fungal infection. Treatment with amphotericin B was started and antimicrobial treatment was continued with liposomal amphotericin B because of an increase in creatinine later. The fever persisted and the patient suddenly developed progressive neurological symptoms. CT scan of the head suggested cerebral infarction and angiography of the extra- and intracranial arteries showed signs of vasculitis. Six days after the onset of neurological symptoms cerebral death was diagnosed. Autopsy revealed non-septate, irregularly branched hyphae in various histologic sections including brain. Absidia corymbifera could be isolated from lung tissue confirming the diagnosis of disseminated mucormycosis. In this case, angiographic findings suggested severe cerebral vasculitis which was in fact caused by thromboembolic dissemination of fungal hyphae. This case underlines the fact that cerebral symptoms in febrile neutropenic patients are highly indicative for fungal infections of the brain.

Brain stem mucormycosis in a narcotic addict with eventual recovery.

In addition to the well-known infectious complications of intravenous narcotic abuse, a much rarer and more recently recognized association between intravenous narcotic addiction and mucormycotic abscesses of the central nervous system has been described. Only four cases have been cited in the literature, with a mortality rate of 100 percent in this group. This report describes a narcotic abuser who presented with obstructive hydrocephalus and a mucormycotic abscess of the brain stem, and recovered. Central nervous system mucormycosis should be included in the differential diagnosis of drug abusers who present with a rapid deterioration in neurologic status.

Hairy cell leukemia and mucormycosis. Treatment with alpha-2 interferon.

Right maxillary sinus mucormycosis developed in a 45-year-old patient with hairy cell leukemia and pancytopenia. The patient recovered with surgical debridement, amphotericin therapy, and institution of alpha-2 interferon as therapy for his hairy cell leukemia. This may be the first case of the use of alpha-2-interferon therapy in a patient with documented systemic fungal infection and hairy cell leukemia and a rare example of recovery from this infection in a hematologic malignancy.

Rhinocerebral mucormycosis: changing patterns of disease.

Eleven cases of rhinocerebral mucormycosis (RM) encountered over a 13-year period were reviewed. Predisposing factors included leukemia (36%), diabetes mellitus (27%), aplastic anemia (9%), myelodysplastic syndrome (9%), and treatment with immunosuppressive medications necessary to maintain solid organ or bone marrow graft viability (64%). Two patients had no predisposing factors. Clinical findings included headache (73%), fever (55%), black nasal eschar (45%), orbitofacial cellulitis (36%), cranial nerve palsy (36%), altered sensorium (36%), and hemiparesis (27%). Seven patients presented with destruction of the paranasal sinuses and local invasion; three with direct extension to the frontal or temporal lobes. Four patients displayed hematogenous dissemination to the cerebrum, brain stem, and cerebellum from a primary pulmonary focus. The seven patients with sinus involvement were treated with aggressive surgical debridement. Two patients with focal intracerebral lesions underwent either open craniotomy or stereotactic biopsy. Amphotericin B was administered intravenously to all patients. Local irrigation via a percutaneous catheter was performed in the seven patients with sinus disease and in one case of intracranial abscess. All seven patients with intracranial infection died, in contrast to four patients that survived with infection localized to the sinuses and orbits. All survivors had been treated with a combination of surgery and amphotericin B therapy. This review demonstrates that RM is increasingly affecting patients with sources of immunosuppression other than diabetes mellitus. Early aggressive therapy to prevent cerebral involvement by this severe infection provides the best chance for a good outcome.
